REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 489,247, dated January3, 1893.

Application filed August 15, 1892. Serial No. 443,126. (No model.)

To all whom it may concern:

Be it known that I, JOHN M. CLARKIN, a citizen of the United States,residing at St. Paul,

in the county of Ramsey and State of Minnesota, have invented certainnew and useful Improvements in Refrigerators, of which the followingr isa specification.

This invention relates to refrigerators, and it consists in theconstruction, combination, and arrangements of parts, as hereinaftershown and described, and specifically pointed out in the claim.

In the drawings-Figurelis a cross sectional elevation. Fig. 2 isalongitudinal sectional elevation, on the line a' .fr of Fig. l, of aportion of one end of the refrigerator through the ice receptacle, andFig. 3 is a front elevation of a portion of the other end, showing thearrangement of the doors. Fig. 4 is a plan view in section on the line yy of Fig.

l. Fig. 5 isa plan View in section on the line e e' of Fig. l. Fig. 6 isan enlarged sectional detail illustrating more fully the construction ofthe butter receiving chambers. Fig. 7 is an enlarged detail illustratingthe manner of constructing the Walls of the refrigerator.

The casing or walls of the refrigerator are formed of an outer shell Ahaving a lining fi of paper or other similar suitable non-conductingmaterial, and an inner shell A2 placed some distance from the outershell, as shown, so as to leave large air spaces between the two shells.This inner shell is also provided with a paper or other suitablenon-conducting lining t2 the two shells being secured at the corners bycorner posts A3, as shown.

Attached to the interior of the outer shell A at suitable intervals arewooden strips i* to form supports for a paper or other similar suitablenon-conducting partition i, while strips i similar to the strips i4 areattached to the inner shell opposite to and projecting toward the stripsi4- as shown, so as to form additional supports to the partition By thissimple arrangement the walls are formed with two distinct and separateair spaces, which insures a much more complete and perfect insulationand at a very slight cost. This construction also greatly decreases theweight, as no heavy non-conducting tillin g is required for the walls.

The ice receptacle consists of a galvanized iron or other suitable pan Bsuspended about midway across the interior of the refrigerator, andprovided with an ice rack B2 upon which the ice rests. The pan issurrounded on all sides by upright guards B3 forming racks to retain theice in place but with sufficient space between them to afford freecirculation of the air, as indicated by the arrows, in Figs. l-2 and 6.The ice `rack B2 is elevated a short distance above the bottom of thepan B by cross strips a, so that the water from the melting ice willfreely flow off through the drainage tubes, as well as to permit the airto freely circulate around the slats, of which the rack is formed. Therear edge of the ice pan does not extend to the back of the interior ofthe casing, but ends at an interior non-conducting partition AAL whichin turn ends a short distance below the top of the casing, so as toafford a passage for the air currents at b, as shown in Figs. l and 2.The lower edge of the partition A4 comes flush with the bottom of thepan B', as shown. Depending from the bottom of the pau B near its frontedge, is a stop strip g which serves as a check to the rising warmercurrents of air and prevents them from flowing upward against thedescending currents of colder air flowing downward in front of the icereceptacle, but which causes them to flow backward and upward behind thepartition A4. The front edge of the pan B does not extend to the frontof the casing but space is left for a series of slatted shelves D',access to which is had through doors D2 in the front of the casing A, asshown.

In the front of the interiorof the casing beneath the line of the panB', are a series of small compartments Fforined by short crosspartitions F2, (see Fig. 4.) and each provided with an inner hinged doorF3 and an outer hinged door F4, the latter formed with suitablenonconducting walls, preferably with two plates of glass cl d? and withan airspace d3 between them. The tops of these compartments are formedof slats e', and with a corresponding slatted grating over each with itsslats c2 registering with the slats e', so that when the slats e2 of thegratings are placed above the slats e', currents can freely passdownward between them into and through the compartments F', as indicatedby the arrows in Fig. 1, but when the grating is moved so that its slatse2 come above the spaces between the slats e', as in Fig. 6, the gratingforms a cut of plate to shut off the air currents. Each ot` the doors F3is connected to its corresponding door F4 by a rod h', so that as thedoor F4 is opened the connected door F3 will be closed, and vice versa,and by connecting each of the gratings to its contiguous door F3 by ashort rod h2, the slats e2 of the latter will also be closed over thespaces between the slats e at the same time that the door F3 is closed,as in Fig. 6. By this simple arrangement, when one of the doors F4isopened all communication between the interior of the compartment F withwhich it is connected and the interior of the refrigerator, is shut offautomatically, so that no substantial portion of the cold air of theinterior of the refrigerator is lost by the act of opening one of thecompartments F', all the cold air that is lost being that contained inone of the compartments.

posed of corresponding slats e2, and adapted.

to be actuated by the opening and closing of said doors, to cover anduncover the spaces between the slats forming the top wall of saidcompartments, substantially as and for the purpose set forth.

In testimony whereofI have hereunto set my hand in the presence of twosubscribing witnesses.

JOHN M. CLARKIN.
